Normally at what age is Menopause occurs?

menopause age is different for each woman, but as a general rule it it occurs between 45/55. The female ovaries have about 400 plus minus (400 divided by 12 = about 33 years.) eggs at the time of birth. When a female reaches puberty and mensuration starts one egg is matured every month and is released for impregnation. Since the start of mensuration is different for different females so is the start of menopause. The girls who started mensuration early will have earlier menopause and so on. So also the number of eggs also determine the time of menopause.
